My Great-grandmother's maiden name was Joanna Mary Kirby, In January 1876 She married William C Cuningham,
at St johns Church,Stafford Westland on the west coast of the South Island New Zealand.
In issue 3223 of the West Coast Times dated 24th of January 1876 under the heading MARRIAGE it states in that announcement
That Joanna Mary Kerby was the third daughter of John Hanley Kirby Esq, Oola Hills County Limerick, and the niece of,
Captain William P Moloney, HM. 74th Highlanders.
I would be most grateful if anyone has information on the descendants of Joanna Mary's two sister's.
Or any descendants of John Hanley Kirby.
I am familiar with Joanna Mary's descendants from her marriage to William C Cuningham.
Thank you in advance. Neil
